On most operating systems, permissions aren't just granted to apps at install time. Rather, developers have to ask the user for permissions while the app is running.

This plugin provides a cross-platform (iOS, Android) API to request permissions and check their status. You can also open the device's app settings so users can grant a permission.
On Android, you can show a rationale for requesting a permission.

Setup #

While the permissions are being requested during runtime, you'll still need to tell the OS which permissions your app might potentially use. That requires adding permission configuration to Android- and iOS-specific files.


Upgrade pre 1.12 Android projects

Since version 4.4.0 this plugin is implemented using the Flutter 1.12 Android plugin APIs. Unfortunately this means App developers also need to migrate their Apps to support the new Android infrastructure. You can do so by following the Upgrading pre 1.12 Android projects migration guide. Failing to do so might result in unexpected behaviour. Most common known error is the permission_handler not returning after calling the .request() method on a permission.


As of version 3.1.0 the permission_handler plugin switched to the AndroidX version of the Android Support Libraries. This means you need to make sure your Android project is also upgraded to support AndroidX. Detailed instructions can be found here.

The TL;DR version is:

  1. Add the following to your "" file:
  1. Make sure you set the compileSdkVersion in your "android/app/build.gradle" file to 31:
android {
  compileSdkVersion 31
  1. Make sure you replace all the android. dependencies to their AndroidX counterparts (a full list can be found here).

Add permissions to your AndroidManifest.xml file. There's a debug, main and profile version which are chosen depending on how you start your app. In general, it's sufficient to add permission only to the main version. Here's an example AndroidManifest.xml with a complete list of all possible permissions.


Add permission to your Info.plist file. Here's an example Info.plist with a complete list of all possible permissions.

IMPORTANT: You will have to include all permission options when you want to submit your App. This is because the permission_handler plugin touches all different SDKs and because the static code analyser (run by Apple upon App submission) detects this and will assert if it cannot find a matching permission option in the Info.plist. More information about this can be found here.

The permission_handler plugin use macros to control whether a permission is enabled.

You must list permission you want to use in your application :

  1. Add the following to your Podfile file:

    post_install do |installer|
      installer.pods_project.targets.each do |target|
        target.build_configurations.each do |config|
          ... # Here are some configurations automatically generated by flutter
          # You can enable the permissions needed here. For example to enable camera
          # permission, just remove the `#` character in front so it looks like this:
          # ## dart:
          # 'PERMISSION_CAMERA=1'
          #  Preprocessor definitions can be found in:
          config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= [
            ## dart: PermissionGroup.calendar
            # 'PERMISSION_EVENTS=1',
            ## dart: PermissionGroup.reminders
            # 'PERMISSION_REMINDERS=1',
            ## dart: PermissionGroup.contacts
            # 'PERMISSION_CONTACTS=1',
            ## dart:
            # 'PERMISSION_CAMERA=1',
            ## dart: PermissionGroup.microphone
            # 'PERMISSION_MICROPHONE=1',
            ## dart: PermissionGroup.speech
            ## dart:
            # 'PERMISSION_PHOTOS=1',
            ## dart: [PermissionGroup.location, PermissionGroup.locationAlways, PermissionGroup.locationWhenInUse]
            # 'PERMISSION_LOCATION=1',
            ## dart: PermissionGroup.notification
            ## dart: PermissionGroup.mediaLibrary
            ## dart: PermissionGroup.sensors
            # 'PERMISSION_SENSORS=1',   
            ## dart: PermissionGroup.bluetooth
            # 'PERMISSION_BLUETOOTH=1',
            ## dart: PermissionGroup.appTrackingTransparency
            ## dart: PermissionGroup.criticalAlerts
  2. Remove the # character in front of the permission you do want to use. For example if you need access to the calendar make sure the code looks like this:

            ## dart: PermissionGroup.calendar
  3. Delete the corresponding permission description in Info.plist e.g. when you don't need camera permission, just delete 'NSCameraUsageDescription' The following lists the relationship between Permission and The key of Info.plist:

    Permission Info.plist Macro
    PermissionGroup.calendar NSCalendarsUsageDescription PERMISSION_EVENTS
    PermissionGroup.reminders NSRemindersUsageDescription PERMISSION_REMINDERS
    PermissionGroup.contacts NSContactsUsageDescription PERMISSION_CONTACTS NSCameraUsageDescription PERMISSION_CAMERA
    PermissionGroup.microphone NSMicrophoneUsageDescription PERMISSION_MICROPHONE
    PermissionGroup.speech NSSpeechRecognitionUsageDescription PERMISSION_SPEECH_RECOGNIZER NSPhotoLibraryUsageDescription PERMISSION_PHOTOS
    PermissionGroup.location, PermissionGroup.locationAlways, PermissionGroup.locationWhenInUse NSLocationUsageDescription, NSLocationAlwaysAndWhenInUseUsageDescription, NSLocationWhenInUseUsageDescription PERMISSION_LOCATION
    PermissionGroup.notification PermissionGroupNotification PERMISSION_NOTIFICATIONS
    PermissionGroup.mediaLibrary NSAppleMusicUsageDescription, kTCCServiceMediaLibrary PERMISSION_MEDIA_LIBRARY
    PermissionGroup.sensors NSMotionUsageDescription PERMISSION_SENSORS
    PermissionGroup.bluetooth NSBluetoothAlwaysUsageDescription, NSBluetoothPeripheralUsageDescription PERMISSION_BLUETOOTH
    PermissionGroup.appTrackingTransparency NSUserTrackingUsageDescription PERMISSION_APP_TRACKING_TRANSPARENCY
    PermissionGroup.criticalAlerts PermissionGroupCriticalAlerts PERMISSION_CRITICAL_ALERTS
  4. Clean & Rebuild

How to use #

There are a number of Permissions. You can get a Permission's status, which is either granted, denied, restricted or permanentlyDenied.

var status = await;
if (status.isDenied) {
  // We didn't ask for permission yet or the permission has been denied before but not permanently.

// You can can also directly ask the permission about its status.
if (await Permission.location.isRestricted) {
  // The OS restricts access, for example because of parental controls.

Call request() on a Permission to request it. If it has already been granted before, nothing happens.
request() returns the new status of the Permission.

if (await Permission.contacts.request().isGranted) {
  // Either the permission was already granted before or the user just granted it.

// You can request multiple permissions at once.
Map<Permission, PermissionStatus> statuses = await [

Some permissions, for example location or acceleration sensor permissions, have an associated service, which can be enabled or disabled.

if (await Permission.locationWhenInUse.serviceStatus.isEnabled) {
  // Use location.

You can also open the app settings:

if (await Permission.speech.isPermanentlyDenied) {
  // The user opted to never again see the permission request dialog for this
  // app. The only way to change the permission's status now is to let the
  // user manually enable it in the system settings.

On Android, you can show a rationale for using a permission:

bool isShown = await Permission.contacts.shouldShowRequestRationale;

Some permissions will not show a dialog asking the user to allow or deny the requested permission.
This is because the OS setting(s) of the app are being retrieved for the corresponding permission.
The status of the setting will determine whether the permission is granted or denied.

The following permissions will show no dialog:

  • Notification
  • Bluetooth

The following permissions will show no dialog, but will open the corresponding setting intent for the user to change the permission status:

  • manageExternalStorage
  • systemAlertWindow
  • requestInstallPackages
  • accessNotificationPolicy

The locationAlways permission can not be requested directly, the user has to request the locationWhenInUse permission first. Accepting this permission by clicking on the 'Allow While Using App' gives the user the possibility to request the locationAlways permission. This will then bring up another permission popup asking you to Keep Only While Using or to Change To Always Allow.
